The present invention relates to improvements in cables or otherelectric conductor engaging terminals.

An important object of the invention is the provision of a conductorterminal'constructed so as to permit a rapid and durable connection ofan electric conducting wire.

A further object of the invention is the provision of a conductorterminal designed to securely engage a conductor and to obviate the useof soldering or other connecting material.

Another obj ect of the invention is the provision of a terminal of theabove character which will be simple and durable in construction andwhich can be conveniently adjusted to conductor engaging position.

Other objects and advantages of the in'- vent-ion will become apparentas the description progresses.

In the accompanying drawings forming a part of this speciiication and inwhich like reference characters are employed to designate correspondingparts throughout the same: f

Figure 1 is a perspective view of the improved terminals operativelymounted upon a supporting base and engaging an electric conductor,

Figure 2 is a fragmentary perspective view of one of the terminals priorto the connection of a conductor therewith,

Figure 3 is a similar view showing the initial connection of theterminals with a conductor,

embodiment o-f the invention, the numeral generally designates aconventional form of terminal base constructed of porcelain or otherinsulating material, the top of the base being formed with conductorengaging ms. "serial No.' 379,552.

grooves andV depressions adapted to receive therein lthe conductorsecuring terminals.

' One portion yof the base topis provided with an arcuate depressiondesigned to support thereinran arcuate, substantially horseshoe shaped,terminal plate 11. An opposed recess inv the basev 10-supports a flatelon-V gated terminal plate 12.

1 Eachof the-V terminall plates 11 and 12 is provided, .atitsroutervedgefportion, with a pair of 'spaced arcuately bentv prongs13- turned upwardly/to,V form conductor engaging projections, Betweenthe prongs 13 is formedA a relatively long` and narrow tongue 14 spacedequidistantly between the prongs and normally assuming an upwardly bentoutwardly inclined position, as shown in Figures 1 and 2.

Each of the terminal plates is also provided with an interiorlythreadedl aperture adjacent the outer edge in longitudinal alignmentwith the tongue 14 adapted to receive therein a terminal screw embodyinga threaded shank 15 and an enlarged head 16. rlhe head is formed with adiametrically eX- tending groove 17 in the top thereof disposed toreceive the tongue 14 in conductor engaging position. The screw head 16is also preferably provided with spaced notches 18 for convenientturning movement thereof.

In connecting a conductor with the terminals, the insulation is removedfrom a portion thereof and the uncovered wire initially positionedbetween the bent prongs 13 and the screw, the head of the screw beingpositioned in an elevated arrangement to receive the conductor wirethereunder. The screw is then threaded tightly upon the conductor wireand disposed so that the groove 17 will assume a longitudinal positionin registration with the extension of the central tongue 14. The tongueis then bent'over the wire and into the groove 17 of the terminal screwto securely clamp the conductor to obviate accidental disconnectionthereof.

Thus, an extremely simple and effective terminal connection is afforded,permitting rapid connection of the conductor or removal thereof withoutthe necessity of soldering the joint between the terminal and theconductor.

It is to be understood that the form of my invention herein shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes as to the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the in vention or thescope of the subjoined claim.

Having thus described my invention, I claim: p l Y In a conductorterminal, a terminal bplate provided with a 'threaded 'aperture there-vthrough, a screw engageable with the a erture having an enlarged headdispose 4to, v

engage a conductor between the head and the plate and provided wthadiametrically'ek tending groove in thetop thereof, a pairv of upwardlycurved prongs extending in spaced position from the outer edge. of theplate adaptedto prevent outward movement of a conductor -n connectingposition between the screw head and the plate, and an elongated tongueprojecting rom Vthe outer edge of the terminal plate between the prongsadjustable to a screw clamping position when bent over the conductoryand tted longitudinally into the groove, in the screw head.

In witness whereof I have-hereunto set my` hand.. f

GEORGES BEDARD.
